Application led August 12, 1824, Serial No. 731,601, 'and in GermanyAugust 25, 1923.

The present invention relates to a petroleum cooking and heating deviceof the well known cup burner type, in which the liquid fuel is caused toevaporate in an open burner while two coaxial perforated plate cylinderswhich bound the Said burner supply the rising petroleum-vapors withsufficient air for theirk complete combustion', while the flow of thepetroleum is automatically regulated to produce a full and pureVblueflame.

The main disadvantage of all known types of cup-burners consists in thefact that a flame several feet high will burst forth, if water entersthe cup which is filled with boiling petroleum, whereby a fire may becaused. rThe entrance of the water may be due to wet pots,vboiling-over,y leaking pots etc. Protective devices lso far.developed'do not afford complete safety and economy, as

*Y 2'0 they permit only lpart of the flame to reach the pot to beheatedand thus decrease theV efficiency of the cooking device. A

It is the main object of the present invention to remove thisdisadvantage, and this is p achieved, and effective protection securedby the vcombination of a burner, ak cap, funnel and discharge pipetherefor, the pipe being attachablev to the funnel to extend centrallythrough the burner. Y

` One embodimenty of the invention is illustrated in the accompanyingdrawing which showsa vertical section through the device.

Thecup, in which the petroleum is caused to evaporate by thel action oft-he heat developed in the burner, is indicated by the numeral 1, while2 and 3 are the inner and outer co-aXial, perforatedplate or sheet metalcylinders. The outerV `cylinder isfirmly connected with the cup lat 2,while the inner cylinder snugly rests upon a spherzo ical surface 1b ofthe cup. '.4 is thedouble bottom through which the lower part of theburner is positively supplied with part of the air requiredV forcombustion. 5 is the funnel which catches any water entering the a.;inside; 6 is thev discharge pipe which by meansvof'afwinged nut 7 alsoserves for fasteningtheburn'er to the frame; 8 is the Y cap fordischarging overflowing water.

I Claim I :o

l-A cooking or heating device comprising the combination-of a burner, acap, funnel and ldischarge pipe therefor, the pipe being` attachable tothe funnel to extend centrally throughthe burner in order to provide foryeffective protection against the entrance of water into the burner. A
